Filed Aug. 3, 1965, Ser. No. 476,909 4 Claims. (Cl. 222-135) The present invention pertains to a pressurized dispenser assembly having va plurality of individual chambers there- The present invention is an improvement over my copending prior U.S. patent application, Serial No. 235,335, filed November 5, 1962, now Patent No. 3,211,343, and entitled, Multiple-Chambered Pressurized Spray Conlrainer.

It is an object of the present invention to provide a pressurized dispenser assembly wherein a plurality of pressurized chambers, each 4having its own valve, are contained within a single housing or enclosure.

It is another object of the present invention to provide a pressurized dispenser of the character described having a cover member secured to said housing which permits the individual chambers to be selectively activated.

It is still a further object of the present linvention to provide a pressurized dispenser assembly having a plurality of individual pressurized chambers, wherein said chambers Icontain complementary groups of dispensable materials, such as preshave lotion, shaving cream and after shave lotion, or paints or various colors or shades.

These and other objects, features and advantages of the present invention will become more apparent |when considered in conjunction with the accompanying drawings, wherein:

FIGURE 1 is a perspective view of the pressurized dispenser assembly of the present invention, wherein said dispenser has three individual pressurized chambers.

'FIGURE 2 is a vertical sectional view of the pressurized dispenser assembly taken on the line 2-2 of FIGURE 1.

FIGURE 3 is a top view of the pressurized dispenser assembly shown in FIGURE 1.

FIGURE 4 is an enlarged partial sectional view of the valve assembly of one of the chambers as shown in FIG- URE 2.

FIGURE 5 is a front view of a second embodiment of the pressurized dispenser Vassembly of the present invention.

FIGURE 6 is a top view of the pressurized dispenser assembly shown in FIGURE 5 FIGURE 7 is a sectional view of said pressurized dispenser assembly taken on the line 7-7 of FIGURE 6.

FIGURE 8 is a sectional view taken on the line 8 8 of FIGURE 5.

Referring now to the drawings, and more particularly to FIGURES l through 4 thereof, there is shown a pressurized dispenser assembly 10, comprising a housing or container 12, preferably made of plastic material and a plurality of individual pressurized chambers 14, 16 and 18, which are preferably made of metal.

Each of the chambers 14, 16 and 18 has a pressurized dispensable material therein, as, for example, a shaving Cream in chamber 14, an after-shave lotion in chamber 16, and a cologne in chamber 18.

Each of the chambers is provided with a valve 20. The valve 20 includes a body portion 22 having a vertical passage or channel 24 therein. The lower part of said body portion has an annular groove 26 in which there is disposed an annular washer 28 made of rubber or other suitable material. An elongated head portion 30 is mounted on the body portion 22 and a tubular nozzle 32 projects laterally from said head. A helical spring 33 ice is mounted upon the upper part of said body portion and is disposed between the top wall 34 of the chamber 14 and the lower edge of the head 30. The head has a passageway 36 therein which is interconnected between the passage 24 and the nozzle 32 to provide communication therebetween, and a radial channel 37 is formed in said body portion in order to provide communication between the vertical channel 18 and the chamber. The pressure within the chamber, in conjunction with the helical spring 33, biases the valve outwardly therefrom and urges the washer 28 against the lower surface of the top wa-ll 34 of said container, thereby sealing the opening 37 and preventing the contents of said chamber from escaping therefrom.

The housing 12 has lthree vertically disposed slots 40 formed in the top thereof, which slots are spaced apart from one another, and the nozzles 32 of the pressurized chambers are disposed therewithin and project outwardly from said housing.

The housing also includes a cover member 42, preferably made of a flexible plastic material, which is secured to the top .thereof and which serves as the top wall of said housing. The member 42 has a plurality of -slits 44 therein, which are positioned above said valve on either side thereof, and which define actuator segments 46; said segments being disposed immediately above the top of the valve heads 30.

When it is desired to operate one of said pressurized chambers, all that need be done is to depress the corresponding actuator segment 46, causing it to abuttingly engage the valve head 30, moving the same downwardly and thus causing the valve body 22 to move downwardly, whereby the washer 23 is disengaged from the bottom surface of the wall 34, while positioning the opening 37 in flow communication with the contents of the pressurized chamber, thus permitting said contents to be discharged through said opening 37, channel 24, channel 36 and the tubular nozzle 32.

It is herein to be noted that if the cover member 42 is sufficiently flexible, then the same can be formed without the slits 44 and the resiliency of said cover member will be suiiicient to permit the same to be vertically distended, thereby permitting said valve to be activated by pressing said member above said valve head, as described above.

Another embodiment of the present invention is depicted in FIGURES 5 through 8, wherein similar parts are depicted by similar to reference numerals.

In this embodiment the chambers 14', 16 and 18 are disposed within the housing 12 and have valves 20'.

The valve 20 includes a body portion 22 having a longitudinal opening 50 into which is force-ttedly inserted a tubular head portion 30 having a vertical passage- 'way or channel 36. The body portion also includes a radial channel 37', which channel is in flow communication with the passageway 36. The lower part of the body portion has an annular groove 26' in which there is disposed an annular washer 28 made of rubber or other suitable material. The body portion also includes an annular flange 52 at the top thereof. A helical spring 33 is mounted upon the body portion and is disposed between the top wall 34 of the chamber and said annular ange at the top of said body portion. A cover plate 54, having a collar portion 56, is connected t-o said chamber and is positioned over the top wall thereof. The collar 56 has an opening 58 and the upper part of the head portion projects outwardly therethrough. The pressure within the chamber in conjunction with the helical spring 33 biases the valve outwardly therefrom, urging the washer 28' against the lower surface of the wall 34 of said container, thus sealing opening 37 and preventing the contents of said chamber from escaping therefrom. The housing 12' is preferably made of a plastic material and has three nozzles 62, 64 and 66 formed integrally therewith and projecting outwardly from the side walls thereof; ysaid nozzles being spaced 120 apart from one another adjacent the top rim 70 of said housing. Three actuator aps 72, 74 and 76 have the outer edges `thereof connected to the top rim 70 immediately adjacent the nozzles 62, 64 and 66, respectively.

Each of the aps 72, 74 and 78 is provided with a lateral member 78 and a vertical collar 80 on the underside thereof, said lateral member 78 having a channel 82 formed therein and said collar having a vertical passage 84, which is in ow communication Iwith the channel 82.

The collars 84 are adapted to have the upper end portion of the valve head portion 30' inserted therein; the aps 72, 74 and 76 being operatively associated with the chambers 14', 16' and 18', respectively, as will become more apparent from the discussion hereinafter.

When it is desired to operate one of the chambers, such as chamber 14', the actuator ap 72 is depressed, causing the valve head 30' to force the valve body 22 downwardly, causing the Washer 28 to be disengaged from the wall 34 and positioning the radial opening 37' in ow communication with the contents of the pressurized chamber 14', thus permitting said contents to be discharged through said opening 37, channel 36', passageway 84, channel 82 and the nozzle 62.

It is herein to be noted that although the present invention has been described in conjunction with three individual pressurized chambers, the number of said chambers may exceed three or be as few as two.

While I have shown and described the preferred embodiments of my invention, there are many modifications which may be made therein by persons skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.

What is claimed is:
